RESUMEN
BACKGROUND: Healthcare associated infections is a global burden and is one of the main causes of maternal and neonatal morbidity and mortality during the time of labour when admitted to the hospital. Healthcare workers' hands are in most cases the vehicle for transmission of microorganisms from patient to patient. Good hand hygiene practices at the bedside are a simple way of reducing healthcare associated infections. The objective was to assess the impact of a criterion-based audit on infection prevention performance and knowledge during vaginal delivery at a hospital in Tanzania. The quantitative findings were discussed with staff to identify barriers and solutions to quality improvement. METHODS: A mixed-method uncontrolled, before and after intervention study by criterion-based audit was performed at the labour ward at Kilimanjaro Christian Medical Centre. Criteria for best practice were established together with key staff based on national and international guidelines. Sixty clean procedures during vaginal birth were observed and assessed by a structured checklist based on the audit criteria. Baseline findings were discussed with staff and an intervention performed including a short training and preparation of alcohol-based hand rub. Hereafter another 60 clean procedures were observed, and performance compared to the care before the intervention. Furthermore, a knowledge test was performed before and after the intervention. RESULTS: Hand washing increased significantly after a procedure from 46.7% to 80% (RR=1.71 95% CI; 1.27 to 2.31), the use of alcohol-based hand rub before a procedure from 1.7% to 33.3% p<.001), and the use of alcohol-based hand rub after procedure from 0% to 30% p<.00l). After the intervention the mean score for the knowledge test increased insignificantly from 59.3% to 65.3%, (mean difference = 6.1%, 95% CI; -4.69 to 16.88). CONCLUSION: The criterion-based audit process identified substandard care for infection prevention at the labour ward. An intervention of discussing baseline findings and a short training session and introducing alcohol-based hand rub resulted in improvements on infection prevention performance.
RESUMEN
BACKGROUND: Health-care-associated infection (HCAI) is a big challenge in both low- and high-income countries. Around childbirth, infection is among the main causes of maternal and perinatal morbidity and mortality. Appropriate hand hygiene practice is a simple and cost-effective way of reducing HCAIs. This study aimed to assess the baseline performance and knowledge of proper hand hygiene during caesarean sections and the impact of interventions guided by a criterion-based audit at a tertiary health facility in Tanzania. METHODS: A noncontrolled, before-and-after intervention study, guided by a criterion-based audit, was carried out. A criterion based checklist was used for direct observations of hand hygiene performance during cesarean section. A self-administered questionnaire was used to assess knowledge on infection prevention. Performance was compared before and after a half-way intervention. RESULTS: At baseline, low-quality hand hygiene performance was observed. Significant improvements of hand hygiene performance were observed for a number of criteria. Long nails: performance reduction from 15 (25%) to 3 (5%) (P=.04), polished nails: from 11 (18%) to 1 (2%) (P=.04), a score increase in hand wash with water from 43.8 (73%) to 60 (100%) (P=.001). Postoperatively, correct glove removal increased from 20 (33%) to 37.8 (66%) (P=.01). Alcohol-based hand rub use increased from 2 (3%) to 21 (35%) (P=.001). The number of health-care workers who did not wash hands after procedure with either water or alcohol-based hand rub reduced from 35 (58%) to 10 (17%) (P=.001). After the intervention, poor knowledge among health-care workers reduced from 7 (39%) to 3 (17%), while moderate knowledge increased from 8 (44%) to 12 (67%). CONCLUSION: Feedback, discussion of findings, training, visual reminders, and distribution of alcohol-based hand rub, as part of a criterion-based audit is a powerful way of improving hand hygiene performance and knowledge in surgical wards.
